Description

ПАВ - смачивател  ДБ, перемешивают и отстаивают. В 1 л воды, полученной перед вторичными отстойниками , содержитс  180 мг тонкодисперсной окгшины и 80 мг масел. Масел в окалине ,не содержитс .Surfactant - wetter DB, mix and defend. In 1 liter of water obtained before the secondary settling tanks, 180 mg of fine oxides and 80 mg of oils are contained. Oils in scale, not contained.

Экспериментальные, данные по содержанию в окалине при введении оптимальных концентраций других неиногенных ПАВ приведены в таблицеExperimental, data on the content in the scale with the introduction of optimal concentrations of other non-inogenic surfactants are given in the table.

Данные по содержанию масел в окалине при различной концентрации в воде ПАВ и установленной оптимальной концентраций примере ПО-11) приведены на чертеже.Data on the content of oils in scale at various concentrations of surfactant in water and the established optimal concentration (example PO-11) is shown in the drawing.

Интервал (0,08-0,2 г/л) количест ВВОДИ1Ф1Х ПАВ обусловлен тем, что нижн   граница С., .вводимых ПАВ различной активности установлена исход  из технических требований по утилизации шламов, согласно которым допустимое содержание (дддп)масел в о. не должно превышать 1,5% (15 г/л) . Верхн   граница C-j интервала установлена исход  из того, что дальнейшее увеличение количества ПАВ уже не оказывает существенного вли ни  на изменение (снижение содержани  масел в окалине.The interval (0.08–0.2 g / l) of the quantity of the INPUT1F1X surfactant is due to the fact that the lower limit of C., the injected surfactants of various activities is based on the technical requirements for the disposal of sludges, according to which the permissible content (dddp) of oils in o. should not exceed 1.5% (15 g / l). The upper limit of the C – j interval is established on the assumption that a further increase in the amount of surfactant no longer has a significant effect on the change (decrease in the oil content in the scale.

Из полученных данных следует, что осветление маслоокапиносодержащих вод с предварительным введениемFrom the data obtained it follows that the clarification of oil-containing water with the preliminary introduction

ПАВ приводит к получению окалины, не содержащей масла,Surfactant results in an oil-free scale,

Этот осадок плотный, хорошо обезвоживаетс , сохран ет сыпучесть и пригоден к утилизации. Масла, не св занные с окалиной, наход тс  на поверхности воды, и их тоже утилизируют . Окалина, полученна  по способу-прототипу , образует осадок в виде слипшихс  комков, внутри которых находитс  водомасл на  эмульси . Така  окалина к утилизации не пригодна .This sediment is dense, well dehydrated, retains flowability and is recyclable. Oils not bound to scale are located on the surface of the water and are also disposed of. The scale obtained by the prototype method forms a sediment in the form of stuck lumps, inside of which there is a water-oil on the emulsion. This scale is not suitable for disposal.
